MATERIAL & DESIGN:The glowing blanket is made of 100% high-quality polyester fiber. The unique design of the blanket is that it can glow in the dark, which is mysterious and interesting. Just expose it to a bright light source or sunlight for about ten minutes. The brighter the light is, the stronger the blanket will glow in the dark. They are extremely soft, warm, and have delicate packaging. The stitching is neat, which is beautiful and durable.
